OverviewIt's hard to retire, even if you're an older thief long past your prime. In 2015, a retired group of jewel thieves came out of retirement to commit the Hatton Garden diamond robbery in London. It was a complex and unbelievable plan which required a lot of planning and a bit of luck to work. One Scotland Yard investigator described the heist as a scheme which most movie goers wouldn't believe. The four thieves got away with more than 200 million pounds worth of diamonds and while they were eventually caught, they had a great time while they were free.
